Specification of Letters Patent.

Application filed July 1?, 19m. ticrlel 1N0. M9302. I

Be it known that l, MATTHEW HENRY Wnrrrannn, a subject of the King of the United Kingdom of Great Britain and ireland, residing at Norton House, Hornby lltoad, Old Trafiord Manchester, in the county of Lancaster, Fngland, have inventedwnew and useful Improvements in Type Bars or Slugs, of which the following is a specification.

This invention relates to the production of type bars or slugs such as those produced in line-casting machines known commer cially under the trade mark Linotype and other kindred machines, and it relates more particularly to those type bars which are intended for use in the printing of tabular matter.

Several means have already been devised for producing the above particularized type bars and the present invention has reference to those means which involve the formation of the rules by a series of short rule sections one or more on each of a number of juxtaposed type bars. In an arrangement of this description it frequently happens that a rule section on one type bar does not fit exactly up to, or in alinement with, the corresponding sections on the immediately ad acent type bars so that a printed impression taken from those type bars would produce a line broken or zigzagged, or both.

Theprincipal object of the present invention is to remedy this defect and it consists in providing means whereby gaps between the rule sections on adjacent type bars can be readily bridged and the said rule sections joined together so as to form a practically continuous rule. I

The accompanying drawings illustrate on manner of, and means for, carrying the invention into practice.

In these drawings :-Figure 1 is a perspective view of an improved matrix for casting a single rule; Fig. 2 is a vertical section of a portion of the same; Fig. 3 is a perspective ,view of portions of two-juxtaposed type bars with a single rule such as would be cast from the matrix shown in Figs. 1 and 2; Fig. 4: is a view showing in end elevation a series of juxtaposed type bars and. a hurnisher being moved thereover; Fig. 5 is a plan of portions of a series of juxtaposed type bars; Figs. 6 and 7 are elevations of a burnishenfor rubbing down: the spurs, these two views respectively representing the said burnisher turned 90 degrees about its longitudinal axis; Fig. 8 is a view similar to Fig. 1 but of a matrix for casting a double rule,

drawings the aforesaid result is conveniently attained by forming the formative cavities 1 of the matrices 2 from which the rule sections are cast, with terminal depressions 3 (see particularly Fig. 2) so as to produce on the resultant type bars 4 short and preferably tapered, spurs or projections 5 which, as shown in Figs. 4, 5 and 9, normally proect above type height, these spurs being situated either at one end only of the respective rule section, or, as represented in the drawings, one at each end oi the said rule section.

When a series of the just described type bars 4 are imposed in the form, with adjacent rule sections in substantial alinement as indicated for example in Figs. 3, a and 5, with the spurs 5 still extending above type height, anygaps existing" between the re spective rule sections can be readily filled up or bridged by burnishing the spurs down to type height, and this can easily be effected by moving a suitable rooved burnisher 6 such as that represents in Figs. 6 and- 7 along the series of rule sections, which operation, besides serving to depress the spurs, as indicated at the right-hand ends of Figs. 4 and 5, also serves to approximately aline the respective rule sections with each other, as will be clearly understood by reference to Fig. 5.

in the case of a double or multiple rule, as indicated for example in Fig. 9, the respective matrices, as shown in Fig. 8, would have two or more formative cavities 1 each like the one previously described,and preferably, the burnisher would correspondmgly have two or more grooves, so that both or all lines of the multiple rule would be dealt with by a single operation of the same burnisher; or, obviously, a single-rule burnisher could be used for this purpose, the diderent lines of the rule being dealt with by successive operations.

lt'may be pointed out that if the spurs 5 are left standing as cast, that is to say, projecting. above type height, they may be'employed for perforating the printed sheets, and in that connection it may be explained that if the said spurs of any given column are intended solely for perforating purposes, they may be of any desired number and located in any desired position for the purpose intended.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is v 1. A type bar having a printing surface and an upstandin spur or projection situated at one end 0 the printing surface and adapted to be bent over to form a continuation thereof. 7

2. A type bar having a printing surface and an upstandin spur or projection situated at each end 0 the printing surface and adapted to be bent over to form a continuation thereof.

section and a spur adapted to be depressed from above down to type height into the gap between adjacent rule sections.

4:. A rinting surface comprising a plurality o juxtaposedtype bars each having in combination a type-high printing rule section and a plurality of spurs adapted to be depressed from above down to type height into the gaps between adjacent sections.

- -In witness whereof I have hereunto set my hand in the presence of two witnesses. MATTHEW HENRY WHITTAKER.
